  • Patent number: 8318507
    Abstract: A method for the separation of particles of different densities using a step-wise gradient density extraction method as described herein where a sample is suspended in a liquid volume of an extracting medium of specific density and the particles that have a density less than or equal to that of the extracting medium of specific density can be recovered from a horizonatally rotatable hollow disk or a removable receptacle within a horizontally rotatable hollow disk designed for such purposes while the particles that have a density greater than the extracting medium of specific density form a deposit which can be cycled through the extraction process in an iterative fashion by varying the density of the extracting medium allowing the recovery of discrete particles of differing densities from a test sample.
    Type: Grant
